Patented oer. 19, 1937 UNITED STATES- PATENT v OFFIE Hermann Heine, Wetzlar, Germany, assignor to Ernst Leitz, G. in. b. 11., Wetzlar, Germany Application January 16, 1935, Serial No.1,984

In Germany February 19, 1934 r 1 Claim; (oi. as- 39) This invention relates to improvements in microscopes and it is the principal object of my invention to combine .with the microscope an auxiliary apparatus as for instance a source of'light 5 rotating about the'microscope axis by means of tube'and objective, a holder for a source of light is so arranged as to'turn about the axis of the A further object of my invention is the provision of a microscope equipped with an extension pipe stem on the objective casing containing an opaque illuminatpr and non-rigidly connected v to a tube to which the connection element for stem and tube is rotatably secured and in which is arranged an angularly arranged mirror refleeting the light rays from the source oi light.

These and other objects and advantages of 25 my invention will become more fully known as the description thereof proceeds, and will then be more specifically defined in the appended claim. e Q Inthe accompanying drawingforn iin'g ama- 30 terial part-oi this disclosure:

,Fig. 1 is a fragmentary side elevation of a 1 microscope constructed according to my invention.

Fig.2isaviewsimilartoFigure lwithasource 35 of light combined with the microscope. I

Fig. 3 is a fragmentary top plan view of the apparatus,-Figure 2.

As illustrated, between the'tube b and the o jective c of a microscope a holder member d 'is 40 turnably arranged and carries a rotatable source 01' light, designated e. Between the support a otthe microscope and the tube b is arranged the tube guide m provided with an angular extension J n at the apex of which a screw is arranged which is designated q. An analyzer f with an optical -.lens system 12 and o is provided between tube b and the carrier for the objective c for the compensationoi.- the length of the tube. As shown in Figure 2, the tube b has a lower a 50 .Stem in which the analyzer f is'located and which extends through the horizontal arm of a bracket attached tofthe guide m. This guide carries the extensionfn supporting the tube b and is adjustable in height by meansoi the screw 55 qwhileahandleractsasastop.

The holder, a has at both or ends formed therewith suitable sockets 13, I4, and in the outer or these sockets, l3, is held the stem 15 of the source'of light e, while through the inner of the sockets, H, the stem I2 01 the tube 1) extends in which the analyzer fis located, so as to allow a relative rotation.

The objective carrier c' has in its tube ii a re- "iiect'or i6 of.a conventional type, and the carrier c has the inner part'oi an extension pipe In 10 connected thereto as shown in Figure 2, which containsthe opaq'ue illuminator h and is connected, as at k,- to a tubular extension 9. The extension plpelll is connected to the tube II which .by means of a suitable socket i1 is suspended from'the stem ll of the tube b. A similar connection is for instanceshown in my Patent No. 1,448,592 of March 13, 1923;

- An opaque illuminator h is arranged in a side extension tube Iii attached to the objective car-' rier and an extension pipe 9 is loosely connected, as at It, to the stem and carries an 'angularly arranged mirror i so that the opaque illuminator participates in the rotation of the source of light about the axis of the microspopeon account of the non-rigid connection between the opaque illuminator and the source 0! light, as the connection k is rotatably connected to pipe or tube g. A light and heat insulating blind I is arranged between the source of light and the microscope.

The operation 01' my apparatus will be readily understood from the above descriptionby inspection of the drawing, and it will be clear that the non-rigid connection between the source 'ot'light which is rotatably arranged with respect to the microscope will ensure a perfect illumination of the object under the microscope at all times.

It will be understood that I have described and shown the preferred form of my invention as one example only of the many possible ways to-prac- 40 tically constructthe same and that I y make such changes in its general arrangement and in the construction of its minor details as come within the scope of the appended claim without departing from the spirit of myinvention andthe principles involved.

Having thus-described my invention, what I.

. claim as new, and desire to secure by Letters Patextension tube are rotatable, a source of light,

and aholder therefor having a tubular stem, a

means to clampwsaid holder to the microscope tube stem relative to which said objective carrier is rotatable, said clamping means being of a nature to permit rotation of theholder and the source of light relative to the microscope tube stem when said clamping means are loosened, an extension pipe on the stem of the holder for said source of light in alignment with said side extension tube, means on the extension pipe for rotating'the side extension tube with the objective car- .iective.
